## Improvements

NuGet was updated to version 2.12.

## Changes in the Linux packages

The Mono packages now depend on `binutils`. This is necessary for the AOT compilation to work since direct object file emission was removed with [commit cc946ea5](https://github.com/mono/mono/commit/cc946ea5b9e3cbb020c66d8986ecd220ca7ba58c) and we rely on the system assembler/linker now.
